Step-by-step explanation:

(-15)/(-18) = 10/x cross multiply expressions

-15x = -180 since both sides are negative we can write without the sign

15x = 180 divide both sides by 15

x = 12

19= X+5*Z-12

what is X and Z?

Answers

Answer:

X = -5Z + 31

Step-by-step explanation:

Subtract 5Z5Z from both sides.

19 - 5Z = X - 12

19 − 5Z = X − 12

2 Add 1212 to both sides.

19 - 5Z + 12= X

19 − 5Z + 12= X

3 Simplify  19-5Z+1219−5Z+12  to  -5Z+31−5Z+31.

-5Z + 31 = X

−5Z + 31 = X

4 Switch sides.

X = -5Z + 31

X = −5Z + 31

Answer:

19=x+5*z-12

19+12=x+5*z

31=x+5*z

then x=26 z=1

Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)

The value of x is 1/5.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3/5 (x − 7/10)= −3 1/4

Now, Solving for x

3/5 ( x- 7/10 )= 13/4

x- 7/10 = -13/4 x 5/3

x- 7/10 = -65 /12

x= -65/12 + 7/10

x= 24/ 120

x= 1/5

hence, the value of x is 1/5.

take a deep breath hold it for some time and then relax your body when exhaling

Don't think Brainly is the place to ask but If your not getting enough sleep, that can be why so make sure to SLEEP and take naps at around 1:00pm and Try to wake up at 3:00pm

Aerobic activity can be calming. Avoid caffeine, alcohol and smoking which act as triggers for the attack. Regular physical activity helps in releasing the anxiety.

Easier ways are to breathe slow and deep breathing is the cornerstone of calm. Start by breathing in and out slowly.

Drink more water. Dehydration may affect anxiety in a variety of ways. And raw fruits and vegetables are the best foods for panic attack because they act as antioxidants in your body.

Done the first two but i dont know how to do the mean of it

Answers

I think the answer for the mean is 6.

To get the mean you have to add up the total number of peas in a pod, then divide the amount you added up by how many pods there are. :)

To find mean:

1) Add up all data values to get the sum

2) Count the number of values in your data set

3) Divide the sum by the count

First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.

4 x 2 = 8

5 x 10 = 50

6 x 18 = 108

7 x 14 = 98

8 x 6 = 48

8 + 50 + 108 + 98 + 48 = 312 total number of peas

2 + 10 + 18 + 14 + 6 = 50

312 / 50 = 6.24 peas per pod

So in our example the mean number of peas in a pod is 6.24.
